|Digital Pi UTM Tracker||
Digital Pi UTM tracking script will store any UTM parameters it finds into a cookie.
The most common scenarios for UTM use are lead source identification and tracking of specific campaign details where multiple visitors land on the same web page, but come from different referrers. It also helps when providing destination urls to third-party agencies, partners, etc. who are sending traffic to your website.
We use the DPI UTM tracking script so that if someone navigates away from the destination page, and the parameters disappear, the UTM values will still be captured upon eventual form fill.
